Well, not sure what to do in your case. I have let "tv" and "dtv" run for hours over here both on my P100 and PPRO 200Mhz. The only thing that I think of is your kernel version or your vga card. Unfortunatly this kind of problem is very, very difficult to track down. I will see what I think of to help you out. Anyone else seeing this kind of problem?
